USB转双串口芯片

CH9103是一个USB总线的转接芯片，实现USB转两个异步串口。每个串口都支持高速全双工，支持奇偶校验，提供部分MODEM联络信号，用于为计算机扩展异步串口，或者将普通的串口设备或者MCU直接升级到USB总线。 • 全速USB设备接口，兼容USB V2.0。\n• 内置固件，仿真标准串口，用于升级原串口外围设备，或者通过USB增加额外串口。\n• 计算机端Windows操作系统下的串口应用程序完全兼容，无需修改。\n• 支持免安装的操作系统内置CDC类驱动程序或者多功能高速率的VCP厂商驱动程序。\n• 双硬件全双工串口，内置独立的收发缓冲区，支持通讯波特率50bps～3Mbps。\n• 串口支持5、6、7或者8个数据位，支持奇校验、偶校验、空白、标志以及无校验。\n• 支持常用的MODEM联络信号RTS、DTR、DCD、DSR、CTS。\n• 支持CTS和RTS硬件自动流控。\n• 支持半双工，提供;
